Through coupling of high-gravity field and high temperature field of combustion synthesis, ZrO2 toughened Al2O3 (ZTA) adding with TiC strengthened iron ductile (ZTA–TiC–Fe) composite materials were prepared by high-gravity combustion synthesis. The composite toughening of Al2O3–TiC ceramic materials was realized, including phase transformation toughening of tetragonal zirconia, zirconia fiber toughening, and metal ductile phase toughening. The results showed that the fracture toughness of ZTA–TiC–Fe composite materials reached 9–11 MPa·m1/2, which was 2–3 times higher than pure Al2O3–TiC commercial tool materials.
